Explanation<br />

A trial in which two or more treatments are evaluated<br />

concurrently in separate groups of patients.<br />

Document upon which the development and authorisation of<br />

medicinal products for the paediatric population is based. It<br />

is presented by an applicant early during the development<br />

of a product to the EMA Paediatric Committee in order to<br />

agree a paediatric development plan.<br />

<strong>Clinical</strong> Trial includes subjects, who are currently patients,<br />

and can also include healthy volunteers.<br />

A dosage form is the physical form of a dose of medication,<br />

such as a capsule or injection. The route of administration is<br />

dependent on the dosage.<br />

Pharmacodynamics is the exploration of what the Medicinal<br />

Product does to the body.<br />

Pharmacoeconomics refers to the scientific discipline that<br />

compares the value of one pharmaceutical drug or drug<br />

therapy to another.<br />

Pharmacogenetics is generally regarded as the study or<br />

clinical trial of genetic variation that gives rise to differing<br />

response to drugs.<br />

Pharmacogenomics is the broader application of genomic<br />

technologies to new drug discovery and further<br />

characterization of older drugs.<br />

Pharmacokinetics is the exploration of what the body does<br />

to a Medicinal Product.<br />

Phase I is the first stage of a clinical trial. It is to ensure a<br />

treatment is safe for people to take, rather than to try to<br />

treat a condition. These trials are very small, (typically<br />

around 30 people), and usually involve healthy volunteers<br />

or sometimes patients. Ref: http://www.mssociety.org.uk<br />

The second phase in clinical trials aims to investigate the<br />

safety and effectiveness of a potential therapy. Usually<br />

between 100 and 300 people will be enlisted to take part<br />

with the aim of determining whether the treatment will be<br />

safe and effective to treat a condition.<br />

If previous trials have indicated a treatment is safe and that<br />

it also shows promise in being able to treat a condition,<br />

phase III clinical trials begin. These involve large numbers<br />

of participants usually from several hundred to several<br />

thousand subjects, and are often spread between different<br />

hospitals and countries. If these trials show that a drug is<br />

safe and effective, the manufacturers can apply for a drug<br />

license.<br />
